i was inspecting my quad from my last crash today, and noticed that the left, lower A-arm was loose. with the bike standing up on end, if u moved the A-arm it would slide up and down a little, i checked the bolts and they were tight. i took off the A-arm and pulled the bushings out and cleaned them off, then greased them and put them back in, but they still moved. i tried taking out the rest of the bearing, but it didn't want to come and i stopped for fear of making it worse. ne suggestions? i've never had this problem and i'm waiting for my service manual to come in.
